Four kinetic models are studied as first-order reactions with flotation rate distribution f (k): (i) deterministic nth-order reaction, (ii) second-order with Rectangular f (k), (iii) Rosin–Rammler, and (iv) Fractional kinetics. These models are studied because they are considered as alternatives to the first-order reactions. The first-order representation leads to the same recovery R(t) as in the original domain. The first-order R∞-f (k) are obtained by inspection of the R(t) formulae or by inverse Laplace Transforms. The reaction orders of model (i) are related to the shape parameters of first-order Gamma f (k)s. Higher reaction orders imply rate concentrations at k ≈0 in the first-order domain. Model (ii) shows reverse J-shaped first-order f (k)s. Model (iii) under stretched exponentials presents mounded first-order f (k)s, whereas model (iv) with derivative orders lower than 1 shows from reverse J-shaped to mounded first-order f (k)s. Kinetic descriptions that lead to the same R(t) cannot be differentiated between each other. However, the first-order f (k)s can be studied in a comparable domain.
